Tammy

A fast-food worker (Melissa McCarthy) gets fired for being an unreliable slob, then comes home to find her husband having a romantic dinner with another woman (Toni Collette, shamefully wasted). At the end of her rope, she sets out with her alcoholic grandmother (Susan Sarandon) on a road trip to Niagara Falls. Co-written by McCarthy and her husband Ben Falcone (who also directed), the movie is as disorderly and obnoxious as its title character. Meanwhile, a top-flight supporting cast (Allison Janney, Gary Cole, Kathy Bates, Sandra Oh, Dan Aykroyd) has little to do but stand watching the star thrash around, then line up at the end for an unconvincing group hug. McCarthy often shines as a supporting actress (remember Bridesmaids?), but as a star, her bag of tricks is beginning to look pretty shallow.
